I was dating a girl w/ a rough past (split home, abuse, etc). We had a very minor verbal disagreement over something, like so minor voices weren't even raised. Then I hear from my friends she is telling people I was abusing her. I ended it right then. She apologized, told our friends she made it up, etc. Nope. Done. Bye. That was HS and my future didn't need that drama-to-be in its wake.
You're stuck after "I Do," up till then you have to know when to cut bait and re-cast... you do have to think with the brain in the cranium some, too.

Would that more HS age guys kept their cranial brain in charge the way you did.
